Hi,
I've just bought a new 120GB WD harddrive for my Sparc Ultra 5, which should replace the old 30G drive that was installed when i obtained the machine.
After partitioning (SUN Disk Label installed, keeping "whole disk") I did a Stage3 installation, Kernel 2.6.13, SILO and so on. Now everything went fine, and I finally shut down the system to switch harddrives.
The new drive now was jumpered as master, the old drive wasn't even connected anymore. After power on, the OBP refuses to boot from that harddisk, instead I get the follwing output: "boot device: net args:" and then it tries to receive arp/rarp packages which produces a timeout.

So I switched back to the old drive, now the machine boots again, and I can mount the new HD.

I'm not quite sure, what causes this behaviour, but I think either the disk doesn't get recognized as a bootable device at all, or the partitioning was wrong.
The old drive has an own /boot partition (16MB, ext2) as partition 1, the new drive has / with 15G, ext3 as first partition and no separate /boot anymore.

The old drive was not jumpered to CS, but doing so on the new drive helped. I was curious what would happen if the jumper was removed completely - and hey: it also works. Thanks for the tip, I would never have thought of the jumpersettings, as it is common nowadays to just set them as supposed

No problem - I dont know why it works this way - but its probably some oddity from the SUN IDE sub system. I cant wait to change mine to SCSI disks and get the speed back _________________Toady
